Myelin visited my office yesterday complaining of numbness in his right leg and face. He has also been experiencing muscle weakness and mild depression. I noticed a delay in his visual response in both eyes. I have referred Myelin to your facility because of possible multiple sclerosis, and I am requesting an MRI of the brain and spine. Please fax the results to me as soon as possible.…
The first step would be the stimulation whether it be air noises, water noises, music or someone coughing. The sound then travel to the outer ear where it is the reflected into the middle ear where it is amplified into the inner ear. The sound is then transferred through the viscous fluid in the cochlea. Inside the cochlea are tubes that are filled with fluid and hair cells. The hair cells are moved by the sound waves and become receptors for the primary auditory cortex. The cortex then processes the sounds into an interpretation. (University of Phoenix,…
Lidocaine is a local anesthetic. A local anesthetic is one that is injected or used at a specific site on your body, like eye surgery. Lidocaine can also be topical, or rubbed into the skin. Lidocaine blocks signals to the brain that are sent by nerve impulses or endings on the skin so the brain doesn’t receive the signal (Jahormi 2012). Lidocaine actually blocks the sodium channels of the cell membrane that are used for signal sending. Removing the cataracts of the eye or a specific skin disease could be treated with the use of Lidocaine. It is mostly used for a quick…

Perhaps the most important factor in a person’s development is his or her family. Family members can shape some one’s thoughts and can make it difficult for a person to fit in one’s environment. In the novel Ceremony by Leslie Marmon Silko, Tayo’s auntie is an antagonistic woman who is concerned about other people’s judgment toward her and her family. Her unfriendly behavior sprang from her low self-esteem and the anger she reproached because her sister’s unruly actions.…
In this paper the author will analyze how neuro processes affect behavior and impact the field of biological psychology. The author will also address the role of excitatory and inhibitory postsynaptic potentials, synaptic transmission, and receptors in producing and regulatory behavior.…
In this assignment I will be looking at the nature of two named physiological disorders. I will explain its sign and symptoms and access possible difficulties involved in the diagnosis of the disorders from their signs and symptoms. The two physiological disorders are coronary heart disease and breast cancer.…
In this assignment I am going to describe two physiological disorder in details, the details that I am going to go into is what the disorder is, signs and symptoms, cause of the disorder, physiological changes as a result of treatment and the factors influencing the development of the disorder, explain the signs and symptoms related to two named physiological disorders, describe the investigations that care carried out to enable the diagnosis of these physiological disorders and assess possible difficulties involved in the diagnosis of the disorders from their signs and symptoms.…
Inside our brain, there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor nerves, which relay messages from the central nervous system, to all the skeletal muscles of your body. The autonomic nervous system regulates the body’s internal environment, which consists of organs, glands, and blood vessels. An example is breathing.…
The human Body is a very complex organism. It is composed of many different organs systems, which are vital for the body to function properly. They work with one another in order to carry out daily life activities and maintain the body’s proper functions. Among these organ systems lies one of the most important, the nervous system. The nervous system functions as the control center of the body, and it is in charge of the activities of the rest of the organs systems and the body’s components (Marieb, E.N. & Hoehn, K.). It helps the body communicate external environmental factors via electrical impulses that are transmitted through cells called neurons. These neurons can be up to a meter long and target a specific effector which it will help…
